IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 150,047, dated April 2l, 1874; application filed February 9, 1874.

To all whom it may concern:

Be it known that I, JAMES R. HYDE, of the city of Troy, in the county of Rensselaer and State of New York, have invented certain Improvemcnts in Cooking Stoves for burning bituminous and other coal, and in warming closets and water-reservoirs, of which the following is a specification:

The nature of my invention relates to improvements in cookin g-stoves for burning bituminous and. other coal, and in warming closets and water-reservoirs, water-tanks for generating steam, their combinations With, and their attachments to, such stoves, reference being had to Letters Patent granted to me for and upon improvements in cooking-stoves andreservoirs, dated March 11, 1873, and June 17, 1873, also, application for further improvements in such stoves, warming-closets, and reservoirs, tiled in the Patent Office January 2l, 1874, and it consists in constructing au airchamber on the sides and ends of the fire-box, divided by a vertical partitionplate near the center, in front. Into this chamber air from the room is admitted, either in front and on.

each side of said partition-plate, or from the bottom of the stove, through ducts placed near the front corners of such stove, to and into such chamber. The air thus admitted into such chamber becomes highly heated, and is used for heating the oven, reservoir, and warming closet. lt passes from such chamber through a iiue at the back ot' the iire-box and in front of the oven, down to and along the bottom and up the back of the oven, to and past a valve to the smoke-pipe, or through a valve in the back-end plate ofthe stove into a iue at the bottom of the reservoir, along the bottom, up the back, and across the top of said reservoir into the smoke-pipe; or it may belet int-o the room through a valve at the top of the reservoir. When the reservoir and warmingcloset are detached from such stove, the heated air may be let into the room through the valve in the rear end plate of the stove. It also consists in the employment of a valve in the front part of the bottom ovenplate; also, a valve in the rear-end plate of said oven; so as to pass a current of heated air into, or into and through, the oven. It also consists in attaching watertanks (in which to generate steam) y to each side of the stove, at the end of the dre-box, connected by tubes with a hollow ring or chamber, located at the top of the heatingchamber, and forming the top part of the tireboX. Into this ring or chamber air is let in from the room, and steam from the watertanks, and such air and steam pass into the dre-chamber in small jets through apertures in said ring, at or near the top thereof. Such heated air and steam will mingle with the gases arising from the burning fuel, thereby aiding combustion, and burning the smoke. In connection with the heating-chambers and hot-air fines, a single smoke or draft tlue is employed, extending from the tire-chamber directly to the smoke-pipe, thus dispensing with diving or return smoke-fines around the oven, all of which is hereinafter more fully described.

Figure l is a longitudinal vertical sectional view of my stove, reservoir, and warming-` closet. Fig. 2 is a plan view of such stove taken at w x, Fig. l, as shown by the dotted lines, having part of the lire-box and most ot' the oven removed. Fig. 3 is a plan view of the rear part of the stove-top A, showing the piece l? in position when the reservoir is re moved. Fig. 4t is a vertical cross-section of such stove taken at y y, Fig. l, showing the water-tanks, heating-chambers, &c. Fig. 5 is sectional views of parts of the stove-top A, having recesses therein 5 also, the bearingpieces of the reservoir, which t into such recesses. Y

Like letters refer to like or corresponding parts in all the drawings or iigures.

A represents the boiler-hole top of a cooking-stove made in any of the known ways, eX- cept as hereinafter stated 3 B, the liuc-space over the oven, from the {ire-chamber to the eX- it-pipe. T is a plate attached to the stove-top, to depress and spread out the current of gases or smoke at the rear part of the oven, before its entrance into the exit or smoke pipe. C is the lire box; D, the ash-pit; E, the oven; F and G, hot-air spaces or flues under the oven and at the back thereof; H, the warmingcloset; I, the water -reservoir, mounted together, and attached to, the rear end of the stove. Around the fire-box C is formed an air-chamber, L, extending entirely around the sides and ends thereof, and may be provided with a vertical partition in front, as at M, Fig. 2. Gold air is admitted into this chamber L through ilues V, extending from the bottom of the stove to and into said chamber L at or near the front corners of such stove, or

through the front plate and on each side of the partition M, as shown at K, Fig. 2. These inlets for cold air should be provided with valves, so as to regulate the quantity of air to be admitted. The air thus admitted into this chamber or space L becomes highly heated, and passes therefrom, as indicated by the arrows in Figs 1, 2, and 3, around the rebox and down the flue N :in rear of said lirebox, and in front of the oven to and along the bottom flue Gr, and up the back flue F to the slide el, and through the opening O into the flue n on the bottom of the reservoir I, and at the top part of the warming-closet up the iue a to and along the ilue n" to the smoke-pipe J 5 or, by the use of the slide -valve 7e, by moving it toward the stove, the air will pass into theV pipe J. Nhen moved from the stove it will pass into the opening or pipe qu. Said heated air will pass through said pipe w to an upper room. 1f such pipe is :not attached to said liuc the heated air will be let directly into the room where the stove is. The heated air, as it passes along the ilue a, expands into the spaces f between the outside wall and the lining t of the reservoir. Said lining t is a little the smallest at the bottom, so that a small space is left all around. The heated air may be let directly into the pipe J from the ilue F through opening O in the slide d, which is so constructed that, by moving the knob c, it will open O and close O, or vice versa; or there may be two separate valves, one for O, the other for O. Instead of valve 7- there may be two valves operated separately. In the hot-air lue or space under the oven are vertical plates R, extending from the stove-bottom to the oven-bottom, plaeedin an angular form, as at R R, Fig. 2, and they are for the purpose of spreading the heated air to ward the outer parts of the oven. There are small openings S in these vertical plates to admit a portion of the current of heated air to the central parts of the oven-bottom. There are no diving or return smoke-fines at the back or under the bottom of the oven. There is a valve, s, in the front part of the bottom oven-plate 5 also a valve, r, in the rear vertical plate of said oven. These valves are for the purpose of admitting a current of heated air into or through the oven, and for ventilating it one or both may be opened at the same time. lhen the reservoir and warming-closet are removed from the stove, the heated air may be let into the 'room or into the smokepipe by the use of the slide d through valve O or O', or two separate valves can be used. There is a chamber, c, all around and forming the top part of the fire-box above the chamber L. There are water-tanks U attached to each side of the stove or at each end of the fire-box.

These tanks are provided with tight-fittin g covers b, also connectingtubes a leading from said tanks to and into said chamber c. Steam is generated in these tanks U, and passes through the connecting-tubes a into the chamber c. Air is admitted from the room through the front plate of the stove, or through the sides of such stove, or through pipes or ducts from below the stove, into the chamber c. The steam and air thus admitted mingle together, and pass through small apertures in the upper part of said chamber 0, in small jets of hot air and steam, into the re-chamber, and there mingle with the gases arising from the burning fuel, and materially aid combustion, and burn the smoke or soot.

In burning bituminous coal much difficulty is found in clogging or lling up the lues with soot, which is obviated in this stove, there being a direct draft only from the fire-chamber to the exit-pipe. v

Fig. 3 is a view of the rear part of the stovetop A, having the piece P iitted therein to make a iinish of the stove-top when the reservoir is not in use. Dotted lines show the space between the projecting parts i of the stove-top A; a-lso the length of the reservoir at that point. The ends of the piece P are fitted into the re cesses j of the stove-top. The reservoir and warming-closet are mounted together, so as to form but one piece, and can be readily attached to or detached from such stove.

By this construction a large saving is obtained both in the shipment and in the setting up of such stoves, reservoirs, and warmingclosets for use.

The manner of attaching the reservoir and warming-closet to the stove is by extending or projecting a portion of the stove-top A at the rear corners, as shown at z', Figs. 1, 3, and

4,5, having recesses therein, (either circular or beveled in. form,) as shown at j or h, Figs. 1 and 5. On each end, near the front corners of the reservoir, are projecting bearing-pieces m formed to tit into the sinks or recesses j or h in the extended or projecting parts t' of the stove-top. The reservoir and warming-closet at the top part thereof` are fitted in between the projecting parts t' of the stove-top, and rests upon the pieces m, which tit into the recesses j in the top A, and against the back part of the stove, and will be .thereby held firmly in position without the use of bolts, screws, ears, eyes, hooks, or slots through the top plate of the stove.

I do not claim the heating-chamber L aroundv the hre-box, or the inlets or ducts for the admission of air therein, or the perforated ring or chamber c, separately, or as claimed in the Letters Iatent granted to me upon improvements in cooking-stoves, water-reservoirs, and warming closets, dated March 11, 1873, and June 17, 1873; nor do I claim what is covered by claims in a pending application for a patJ ent upon improvements in cookingstoves, res-Y ervoirs, and warmingclosets, led January 2l, 1874. I do not claim the particular ues or Valves about the reservoir, as claimed in said patents or application, except in new combinations or connected with new devices.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. A cooking-stove, which has only a direct draft from the fire-chamber to the exit-pipe, and with or without the oblique plate T attached to the top plate near the pipe-collar, the heating-chamber L around the fire-box, in combination with the lue N in rear of the firebox, the fine G under the oven, the flue F at the rear of the oven, valves O and O', substantially as and for the purposes herein described and set forth.
